Fabrication of layered double hydroxide/photoresponsive dendron nanocomposite multilayer film by electrostatic layer-by-layer assembly

A novel inorganic–organic nanoscopic multilayer film consisting of exfoliated MgAl-type layered double hydroxide (LDH) nanosheets and anthryl dendrons [i.e., poly(amidoamine) dendrons with an anthracene chromophore group at the focal point] was fabricated using an electrostatic layer-by-layer (LbL) assembly. UV–vis spectroscopy and X-ray diffraction analysis indicated the successful LbL growth of dendron/LDH multilayer films. Furthermore, fluorescence spectroscopic analysis indicated that the dendrons are present as a monolayer between LDH nanosheets in the film.
